I can choose from two main dishes of pizza and ferocious putty, so I will eat pizza. Then your decision is based on free will, the decision is pre-determined. In order to fully understand if your action is derived from free will or determinism it must first be defined for each item. The determinism is that everything will happen due to some reasons and determinants that can be observed and measured. In short, determinism does not mean predicting the future.
Discussion of free will is classified / marked in most cases as a discussion between "free will and determinism". This means that if determinism is incompatible with free will (if it is the case), it just needs to indicate that determinism does not necessarily apply, so that automatic possibilities are automatically opened It is a misunderstanding. In other words, when someone opposes free will, many people return to the idea that the universe may not be deterministic, denying this free will becomes their free will and savior. In the philosophical world, the concept that uncertainty contributes to liberation of free will is called free will of liberals (not to be confused with economic / political standpoint). On the other hand, people who accept determinism but still believe in free will be called compatible, and in most cases do this through a defined shift of the term "free will".
Discussion is often called "free will and determinism", but this is a wrong dichotomy. In other words, if the universe is deterministic, such a rule can exclude free will, and if the universe is not dominated by the determinism of free will, this is not true . This is not a fact. Such lack of certainty opens up "possibilities" for free will. This means that the label of "free will and determinism" is not sufficient for discussion about free will. That is why I have marked myself as a discrepancy not as a solid determinist. Not just determinism
Instead of focusing on just determinism, a better label for discussing free will may be "free will and determinism or non-determinism". Historically, many of the past free skeptics have adopted a more solid deterministic position against free will. Difficult determinism means that they believe that the universe is deterministic and that free will and determinism can not work together. Then the fact that there is quantum physics where the deterministic nature of the universe is questioned by the interpretation of uncertainty and the deterministic interpretation needs to be "non-native" is an intuition of long-term transient behavior It is a view contrary to that.
